Hey guys, I am looking into trying to dominate in my area for computer repair, last I had heard on this subject to avoid being penalized it would be best practice to only add one or two separate pages at the most for different local areas. Here in Queens, NY there are many cities so that would be risky to try to cover all areas.
Start with your immediate area and target keywords with geolocation when you write something about the business. This is to help you become an authority when people search.
